Description

Technical Field

[0001] The utility model relates to the technical field of hoisting, and particularly relates to a hoisting device. Background Art

[0002] When mechanical equipment is under maintenance or installation, it is usually necessary to lift it through equipment such as forklifts and cranes. However, due to the existence of sites where forklifts and cranes cannot be used, such as non-ground floors, indoor environments, etc., at this time, manual operations are usually required. And manually carrying and lifting mechanical equipment has a large labor intensity and low efficiency. Therefore, various simple hoisting devices have emerged in the prior art to assist in hoisting mechanical equipment to a designated area for the next operation. However, the traditional hoisting method is to directly connect the mechanical equipment with a single lifting rope for hoisting, which will inevitably cause rotation during the hoisting process, resulting in the winding of the lifting rope and being not conducive to disassembly. At the same time, during the hoisting process of the lifting rope, friction is likely to occur between the lifting rope and the mechanical equipment, and the connection is not firm. The lifting rope may slip off, causing the mechanical equipment to fall, having potential safety hazards. Content of the Utility Model

[0024] Referring to Figures 1 to 4 , what is disclosed in the embodiment of the present utility model is:

[0025] A hoisting device, including a lifting member 1 and sling belts 2 provided at both ends of the lifting member 1. The lifting member 1 is used to pass through a mechanical device 3 to carry the mechanical device 3, and the sling belts 2 are used to transmit on the lifting member 1 to drive the mechanical device 3 to lift and lower;

[0026] At least two groups of limiting members 4 are provided at both ends of the lifting member 1. Each group of the limiting members 4 includes two, and there is a preset distance adapted to the width of the sling belt 2 between the two limiting members 4. The limiting members 4 are penetrated through the lifting member 1 and a part of them protrudes downward from the lifting member 1.

And because the mounting seat 6 is arranged at both ends of the lifting member 1, the distance between the abutting top plates 5 at both ends of the lifting member 1 can be adjusted, so that the distance between the abutting top plates 5 at both ends can match the mechanical equipment 3 within a certain range, thereby restricting the mechanical equipment 3 from shifting during the lifting and lowering process of the lifting member 1.

[0029] A plurality of first mounting holes 8 are evenly arranged at both ends of the lifting member 1 along the length direction of the lifting member 1. At least two second mounting holes corresponding to the first mounting holes 8 are formed in the mounting seat 6. A mounting pin shaft 9 is penetrated through the second mounting holes.

The upper hook of the chain block 13 is connected to the hanging plate. The movable crossbeam 11 is an I-beam crossbeam. The slide crane 12 is movably arranged on the movable crossbeam 11. Wherein, both ends of the movable crossbeam 11 are connected to the lifting frame 10 by bolts. In addition, in this embodiment, the slide crane 12 can also be an electric slide crane, and a controller electrically connected to the electric slide crane is arranged on one side of the lifting frame 10, and the electric slide crane is controlled to move by the arranged controller.

[0032] A plurality of universal casters 14 are arranged at the lower end of the lifting frame 10, so that the lifting frame 10 can drive the movable crossbeam 11 and the mechanical equipment 3 hoisted on the movable crossbeam to move, thereby assisting in hoisting the mechanical equipment 3 to a designated area for the next operation.

In this embodiment, there are 2 lifting members 1, and they respectively pass through the front and rear sides of the mechanical equipment 3 and drive the mechanical equipment 3 to lift and lower simultaneously to prevent the mechanical equipment 3 from shifting.

[0036] 2. Then install the mounting seat 6 and adjust the top plate 5 on the mounting seat 6 so that the top plates 5 on both sides of the lifting member 1 can respectively abut against both sides of the mechanical equipment 3.

[0037] 3. The staff controls the chain block 13 to drive the lifting member 1 to rise, thereby lifting the mechanical equipment.
